While the RS-4 was debuted as Yoshimura's premier exhaust for off-road racing applications, they couldn't stop there. They have mated this sophisticated and stylish muffler to compliment the styling of the new Kawasaki Ninja ZX-6R. The RS-4 pentagonal shaped muffler features a carbon fiber end-cap, two-staged stepped baffle and striking good looks.

The RS-4 muffler features a new front cap design that functions as a poly-resonant chamber, thus creating a more quiet muffler with improved mid-to-top end power.

Along with improving sound and power, this system moves the muffler weight lower and closer to the bike for improved handling and weight distribution.

Note: This exhaust is CARB compliant. Please check local laws before purchasing. Some modifications may be prohibited in some states.

Yoshimura RS4 for 2013 Kawasaki Ninja 636 zx6r
I bought this exhaust in Carbon fibre can + tip to replace my other slip-on (M4 GP funnel type), because it was WAAAY too loud for me. This yoshi pipe mounts up to the passenger pegs, and comes with all the necessary equipment. (black heat shield that doesn't turn purple too!)
This is a true slip-on, as in it does not remove the pre-chamber.
It looks good, refined and most of all clean. The sound is awesome; it is louder than stock, and has a nice little growl. My friend has the Leo Vince slip-on on the same bike, and this yoshi exhaust just looks so much nicer.
I'd recommend it again.

Beautiful exhaust!
I had my slip-on options down to the TwoBros, and the Yoshimura RS-4. I choose the RS-4 because I was worried about noise. After the install, which was very easy, I'm happy for my choice. I love the looks, and it's only slightly louder than stock. I was also surprised to feel an extra kick in low gear on acceleration. Beautiful exhaust, and it does what it's supposed to.
